I wouldn't run a 48t without a 10t in the back. It's not the extremes I'd worry about. It's long 35-40 mph false-flat descents that would put your legs into a crisis. And as you said, most flat sprints would be out of your wheelhouse unless you pride yourself on your cadence. 100 rpm on the pedals with a 48x11 will only get you ~34 mph. If you could bump your cadence to 120, you'd be touching 41 mph. 120 rpm in a dead sprint in the Cat3 field isn't unheard of, but it's uncommon.
